The expression 12x+15x-11x can be combined because of which property

marshall27 [118]

Answer:

The expression $12x+15x-11x$ can be combined because of the commutative property of addition.

Step-by-step explanation:

A monomial is a number, a variable or a product of a number and a variable where all exponents are whole numbers. That means that

$12x+15x-11x$

all are examples of monomials.

The commutative property of addition says that changing the order of addends does not change the sum.

If we add $[(a + b)+ c]$ or $[a + (b + c)]$ , the result will be same.

Therefore,

$12x + 15x - 11x = (12 + 15 - 11)x\\12x + 15x - 11x = (27 - 11)x\\12x + 15x - 11x = 16x$

Answer: $n = -12$

Step-by-step explanation: $n - \frac{2n - 3}{9} + 2 = \frac{2n + 1}{3}$

$\frac{9n - 2n - 3 + 18}{9} = \frac{2n + 1}{3}$

$\frac{7n + 15}{9} = \frac{2n + 1}{3}$

$9(2n + 1) = 3(7n + 15)$

$18n + 9 = 21n + 45$

$9 = 3n + 45$

$-36 = 3n$

$-12 = n$
